Abstract Extensive investigations into structural, magnetotransport and magnetic properties of granular thin films with a thickness of 20 nm based on Co and Ag in a wide range of component concentrations were carried out: 17 ≤ x ≤ 89 where x is at.% of Co. The samples were obtained by the method of electron beam co-evaporation using two independent electron guns at room temperature. The correlation between the structural-phase state and magnetotransport and magnetic properties was established by TEM method. The threshold of structural percolation in granular films was observed for x ≈ 60%. At lower concentration x 70%) the films demonstrated anisotropic magnetoresistance (AMR), which was assumed to be associated with the appearance of ferromagnetic interactions between the cobalt granules.

颗粒状Co Ag100-合金薄膜结构状态与磁阻性能的相关性

摘要 对基于 Co 和 Ag 的 20 nm 厚颗粒薄膜的结构、磁传输和磁性能进行了广泛研究，成分浓度范围很广：17 ≤ x ≤ 89，其中 x 是 Co 的原子百分比。样品是在室温下使用两个独立的电子枪通过电子束共蒸发的方法获得的。通过TEM方法建立了结构相状态与磁传输和磁性之间的相关性。对于 x ≈ 60%，观察到颗粒膜中结构渗透的阈值。在较低浓度 x 70% 时，薄膜表现出各向异性磁阻 (AMR)，这被认为与钴颗粒之间出现铁磁相互作用有关。
